描述

See attached sources. I can reproduce this issue with .Net Core 3.0 and .Net Framework 4.7.2

The second call to OnFormClosed() seems to be a side effect of shutting down the modal message loop that was created to run the child window.

研究方向: 研究WinForms中FormClosed事件的触发机制和模式消息循环的关闭。检查是否由于关闭所有者窗口导致拥有者模式窗口的FormClosed事件被触发两次，原因是消息循环终止。
